About

Life in San Lorenzo

This is a solidly middle-class East Bay suburb that works well if you want Bay Area proximity without the intensity of San Francisco or the sprawl of further out. The median home price sits around $847,000 and median rent around $2,200, which is expensive by national standards but reasonable for the Bay Area—and you get more space here than you would in trendier neighborhoods. Jobs are available locally and the 32-minute average commute is manageable for the region, though like most of the Bay Area, you'll definitely need a car.
